Chronic bronchitis

Chronic bronchitis is a long-term condition characterized by inflammation of the bronchial tubes, which carry air to and from the lungs. It is usually caused by smoking or exposure to other lung irritants such as air pollution, dust, or chemicals.

Symptoms of chronic bronchitis include cough, sputum production, and shortness of breath. Treatment options may include medications to manage symptoms, quitting smoking or avoiding lung irritants, and pulmonary rehabilitation to improve lung function and quality of life. In severe cases, supplemental oxygen therapy or surgery may be necessary.
